,n Application October 18, 1946,- Serial No.' 704,277 z claims. (ci.13s- 420) This invention relates to fabrics and methods of theirmanufacture. v

The creation of spun glass posed the problem of producing fabrics whichconsist entirely of glass bers. Such glass fabrics could be utilizedmost eectively for a variety of purposes in view of theirnon-inilammability, for example, as curtains or draperies for hotels,theaters, public halls, laboratories, exhibitions, public conveyances,as well as in homes. However, it was found impossible heretofore to makeall-glass jacquard fabrics which would be of sufficiently attractive andornamental appearance so that they could find ready acceptance in theuse of draperies and the like. The reason for this situation resides inthe inherent qualities of glass threads which make it most diicult ifnot impossible to provide fabrics which are not too heavy in weight andwhich show surface texture of suiiicient den-sity and depth needed in adecorative fabric.

It is therefore, an object of the present invention to provide anall-glass jacquard fabric having these properties to enable the use ofthe fabric for curtains, draperies and other decorative purposes.

Other objects of the present invention will become apparent in thecourse of the following specii'lcation.

The present invention is based in part, upon my discovery, that theutilization of the so-called ratine eiect in glass yarns makes itpossible to weave a jacquard all-glass fabric which is not too heavy inweight and is most attractive in appearance and adapted-to carry alldesigns capable of being produced upon a jacquard.

According to a preferred embodiment of the inventive idea, the ratineeffect is embodied in the filling, While the warp may consist of astraight two ply filament yarn which may be colored, if desired.

It should be pointed out in this connection that the ratine effect inits broad aspect is attained by twisting together threads of differentlengths with the result that one thread is wound around the other in aform approximating that of a sine curve. Then the resulting yarn insteadof being smooth will have the eifect of a yarn with naturally protrudingfibers. Thi-s eifect is particularly important in order to produce thedesired depth of texture which cannot be obtained with the use ofstraight spun glass filament, since the ratine yarn with its roughsurface gives the ornamentation a raised appearance that otherwise wouldnot be possible.

The appended drawing consists of a rdiagram illustrating the followingexample of a vfabric made in accordance with the'present invention, saidexample being given, however, solely by way of illustration and not byway of limitation.

A fabric is woven on a jacquard with its warp I consisting of a straightcolored 450 double two ply spun glass yarn. The filling 2 consists offancy spun glas-s ratine yarn which vis composed as follows (based on 10inches of yarn) The loop thread consists of 2 ends of 450 single two plythread-4 to 5 turns per inch S direction, 10 to 10.6 inches of yarn,preferably-10.35 inches of yarn.

The base consists of 1 end of 100 two ply thread 9 to 10 turns per inchS direction, 14.5 to 15.2 inches of yarn, preferably 14.85 inches ofyarn.

The loop thread and the base are twisted together approximately 15 to25, preferably 201/2-21 turns per inch S direction.

The binder consists of 1 end 450 single two ply thread-4 to 5 turns perinch S direction, 10.2 to 10.8 inches, preferably-10.5 inches of yarn.

The binder is twisted with the combined loop thread and base 10-11 turnsper inch Z direction, thereby producing the completed ratine yarn.

The ratine yarn in the fabric may be white, While the warp is colored,as stated above. However, the filling may be also colored, if desired.

It is apparent that a satisfactory ratine yarn can be produced eventhough there may be some deviations from the above given figures. Forexample, the respective lengths of threads may vary at least to theextent of 0.3 inch on the basis of 10 inches of yarn. The number ofturns with which the base and the loop thread are twisted may vary up to5 turns either way. 'I'he individual components of the yarn, namely, theloop thread` the base and the binder may be each twisted a somewhatlarger or smaller number of turns, namely, at least two turns eitherway. Other possible changes will be apparent to those skilled in theart.

A jacquard all-glass fabric made in accordance with the describedexample is comparatively light in Weight, so that it can be convenientlyused for draperies, curtains and for a variety of other purposes. Thefabric has a most attractive feel and appearance and may be providedwith any suitable ornamentation.

It is further apparent that other variations and modications may be madein the above example without departing from the scope or intent of thepresent invention; all such variations and modications are to beincluded within the scope of the present invention.

What is claimed is:

1. As a new article of manufacture, an all glass jacquard fabric havinga warp consisting of glass yarn, and a, filling consisting of glassratine yarn, the nlling based on ten inches of yarn, including a loopthread consisting of 2 ends of 450 single two ply thread 4 to 5 turn-s'per inch S direction, 10 to 10.6 inches of yarn, a base consisting of 1end of '100 two ply thread 9 to 10 turns per inch S direction 14.5 to15.2 inches of yarn, the loop thread and the base being twisted togetherfrom 15 to 25 turns per inch S direction, a binder consisting of l end450 single two ply thread 4. to 5 turns per inch S direction 10.2 to10.8 inches'of yarn twisted with the combined loop thread and.v

base -11 turns per inch Z direction.

2. As a new article of manufacture, an all glass 4 10.35 inches of yarn,a base consisting of 1 end of two ply thread 9 to 10 turns per inch Sdirection 14.85 inches of yarn, the loop thread and the base beingtwisted together 201/2-21 turns per inch S direction, a binderconsisting of 1 end 450 single two ply thread 4 to 5 turns per inch Sdirection 10.5 inches of yarn twisted with the combined loop thread andbase 10-11 turns per FRITZ KLOECKENER.
